Redundant Computing Instance Grouping for Railway Safety

The patent segments the system into processing units, where each unit processes messages independently without requiring synchronization with other units. Only the final results from each processing unit are compared, rather than comparing every intermediate message exchange. This segmentation reduces the computational overhead of synchronization while maintaining functional safety through result comparison.

The patent extracts the voting/comparison operation from the internal message processing flow. Instead of comparing every message between redundant instances, only the final output messages are subjected to voting. This extraction eliminates unnecessary comparison operations during intermediate processing steps, significantly reducing computational overhead while preserving safety through final result verification.

The patent segments message processing into independent processing units, where internal messages are processed without external comparison. Only the output of each processing unit is subjected to voting. This segmentation dramatically reduces the number of comparisons required while maintaining integrity verification at the appropriate boundary levels.

The patent extracts the voting mechanism from the internal message exchange process and applies it only to final output messages. This extraction eliminates the computational complexity of comparing every intermediate message while preserving integrity through targeted comparison of final results, which is sufficient for functional safety.
